Hi aspirant!

There is no age limit to be eligible for JEE Main 2019. However, candidates need to pass 10+2 or the equivalent examination in 2017 or 2018. Candidates appearing for 10+2 or equivalent exam in 2019 are also eligible to apply irrespective of their age.

JEE Main candidates can appear in the exam for three consecutive years. Since the entrance will be conducted twice a year, the candidate can choose to appear in both the attempts. However, the attempt for a particular academic year will be considered as One.
